Very unlikely, IMO - as Rob points out, they are rather splendid already.
Also, a period of rest is usually needed after a boob op to allow things to heal. I have Kate on my HL and she has always been active whenever I have checked. I'm sure we will soon find out as she is a member here and may well reply to this post to let us know. Also, she is due back in Bristol on 22nd Nov, so we can then find out for ourselves.
