Not hugely serious essence costs, I'd think-- just 1 per leg replaced, so 2 essence give or take 'ware quality. I'm quite sure that it would indeed be best handled as a drone set up for DNI. Most of my questions revolve around cost and availability, as well as speed and capacity.
My point is that it is likely to be more than just the replacement of two legs, because you aren't just replacing them with two legs, you're replacing them with four legs and a flank.
I'd imagine there are going to be added essence costs for this sort of thing to support all the extra 'nerves' that they'll have to throw in you to be able to operate the legs properly and feel your flank or extra legs. I mean, there is likely to be some reason that legs are replaced with legs and not... say tank tracks or a motorcycle or something.
