God no! I'm not that brave I'd be worried about trashing my hard work 
Don't think I'm good enough to compete (except for my bit of the queen's highway as the need arises  )

It seems that there are various solutions available for this problem, if indeed it is a problem.
Quite often a pointer to the answer can be found in defining the question. Before that can be done a number of decisions need to be made, and those
will depend on such things as
the intended purpose of the car
the funds available
the time available
the facilities available
how soon the project needs to be completed
etc
etc
etc

Okey Dokey:
the intended purpose of the car - road use for fun
the funds available - not many 
the time available - see next but one point
the facilities available - cold, cramped and cluttered garage
how soon the project needs to be completed - ASAP if I'm to avoid the IVA
So I think it's a case of 'getting on with it' and see what happens.
Oh, and BTW, thanks for all the input guys, feel free to comment at will (whoever will is )

I was building a +442 and I wanted to keep the original mx5 track which meant custom wishbones. I also moved the fu tubes
FYI The tube was bigger at 3/4"x1/8" wall CDS tubing.

Did U move the FU tubes b4 or after the chassis had been built?

actually I built it arse about face, I built the front angled assembly(LA and LB) then built the wishbones between an adjustable position jig holding
the hub/upright and the suspension brackets on LA and LB.
It was only then I made and fitted the FU tubes to the free suspension bracket attached to the free end of the top and bottom bones. Does that make
sense??
so to asnwer your question I changed their position before the chassis was finished
Check out my build diary below for some pics

Yep, makes total sense. Trouble for me though is that I have already welded in FU1 and FU2 so it would mean cutting/grinding them out and making new
ones. I am not sure what impact that would have on strength around that area?
Also, wouldn't that affect the angle of th FU tubes wrt the chassis bottom?

Haven't you had to do that already at some point in your build? Excellent.
Get a thin cutting disc for your angle grinder and go for it. Done properly it won't have any affect on the strength.

Thanks for that.
Nope, not had to do that yet, not due to error anyhow, just to alter the side rails to my liking.
So far been really lucky with warping etc, but there is still time
Think I'll sleep on it and make a call tommorrow.

to be honest i think you could just build your custom bones to the site where your FUs are now and not worry about the ratio's.
if you are worried about strength throw in an extra gusset or strut like i have with my top bones
if you are worried though its really no big deal to chop out the FU's and follow the kind of custom bone route i did, it was really easy.
I wont lie its was time consuming I spent a week of days doing little else. I was really please with them though
