Of course, nothing is going to stop you from making a BODY 2, 210 cm high one, but it wouldn’t look proportional, unless given extra ballast. Hey, these are ACPA-sized.
There’s nothing to stop you from changing your look (and Attractiveness) when you feel in mood – if you can afford it. However, you cannot “resell” your former look nor store it anywhere – all the covers are tailored to a specified borg, and cannot be used on another, thus if you choose to change your look, the money you’ve invested in the previous one are lost. As for HL, a new face costs you 1D6 HL, of course being an FBC reduces this to a simple 1. ATTR changes make you loose ATTR if this was upping ATTR only, as it was when you were converted.
RealSkinned, ExoDermed and TrueSkinned FBCs, as well as SuperChromed (and even plastic covered) models can be made physically attractive. The price is to be paid for every point of ATTR. The beginning point is 0. You can be made of any ethnic type for no extra cost (if you still do have ethnic type. ).
Surgery cost (and effect) varies due to quality – poor quality is 50% cheaper (but you look like your generic surfer, and it is Average to spot), then you have more advanced variants (Difficult is 100% more expensive, Very Difficult 300%, and Impossible 500%).
ATTR can be made over 10 (yes !) – such FBCs are usually referred to as artbodies (artistic bodies – projected by artists to be of superhuman beauty). However, nothing comes free – a body that is more slender than whatever the Nature approved does not work well, and tend to have difficulties with stability and motoric control. Reduce REF on 1 to 1 basis (-1 REF for every ATTR point over 10).
I’d suggest limiting ATTR to the max value of 12. However, if one wants to allow even more radical beauty, the cost suggested would be to increase by 10000 eb per point, e.g. ATTR 13 would be 20000 eb / point, ATTR 14 30000 eb per point, and so on. Still, I have trouble with imagining myself an ATTR 12 person, let alone an ATTR 16 one.
There’s a question on how increased beauty would affect one’s humanity (look at the famous people who had changed their appearance a lot, and tell me that Michael Jackson was sane). If you look again (roughly) as you’ve looked before becoming FBC, there’s no HL on that.
However, additional ATTR is as many D6 HL as ATTR points, less https://www.maxloan.org/payday-loans-co one (so +1 ATR is D3 HL, +2 ATR is 1D6, +3 is 2D6 and so on). Of course this is reduced as for all HL when you’re a FBC, so it is not so awful. There’s no additional HL for having new face (if you already have new body, having new face is not any longer an issue).
On the other hand, if you look like a human, it’s good for your mental health. With a face made well enough you can even watch yourself in the bathroom mirror in the morning and not be able to remind yourself whether you are a fleshie, or a ‘borg. And you have a fair chance of finding a sexual partner, which is very important to humans, canned or not.
This is a fact : if you want to hide your superhuman performance, or try to pass as a regular human / cheap ‘borg, then moving with inhuman speed and insanely short reaction time isn’t a good thing. However, it’s not a much problem : usually you move at your top-edge only if you have to. There’s not much point in keeping your reflexes low when you’re already in combat, right ? If you’re even more concerned with it, you can go for specialised software that will block your REF on a pre-set level (usually 6-8) and let it go on full power when issued a mental command. Such software can cost up to 500 eb.
