wanna swap corners! help/pointers appreciated

HI all. Just got a new (to me) 2004 1.2 HTP. Well maintained and for a great price. I have years worth of detailed invoices,  all from the same garage. Less than 76k on the clock with decent feeling clutch
When reveiously enquiring about a different fabia, regarding stiffening her up, I was told before to "swap the entire corners from a VRS" - I like this idea for this ikkle car also.

I can see my front discs will need doing next time AND the rear corners have drums, so VRS brakes would be lovely.

there are several breaking VRS's on that famous auction site but unsure what to ask for and what a good price to pay is.

Does asking , "How much for the entire front corners? from the leg down to the hub, including all the discs,calipers,hoses etc?" ??? Would I be better off asking for wishbones also? (mine have a lot of surface rust that I haven;t explored yet)

Is it easy to swap drums for discs on the rear? will I need different brake pump/abs unit? is it easy to do, once the new lines are flared and in-situ?
