re-drilling alloy rims-stud pattern?

i'm looking at purchasing a set of alloy beadlocked rims but the only prob is they're 5 stud. the PCD is the same as the toyo/Nissan and the hole thru the center of the wheel is slightly smaller, which can be machined out easy enough.
we will be able to utilise 1 of the original holes and just drill 5 new ones to suit. would i have to get the holes not being used filled in with weld or is it best to leave them? not sure if welding would create stress fractures or not? i've got access to a machine shop so thats no problem but just need some opinions if this process has been tried and tested...

NB - what you propose is illegal for road use - if that is an issue.
It is possible though, as long as the mounting face of the rim is solid. Many rims are not.

will only be used for offroad/comps so thats not an issue. not sure how thick the mounting faces are, but thats a valid point so will have to find out. cheers

ive done this on steel and alloy rims,
weld 4 of the holes up. then mark the new 5 holes and drill.
if you want it done correctly, after you have welded them take them to a wheel repair shop and have them re-drill the 5 new holes.
there is enought steel/alloy around the new holes for it NOT to be a problem/dangerous.
There are many of " multi fit" wheels out there aready that are holey'er than yours

do you think it would be necessary to weld up the original holes or could i get away with leaving them? the only 2 that would get close to the new holes would be about 15mm between the hole centers, if that makes sence?

i welded them up, you can leave them be.
I have seen aftermarket wheels with holes so close they did not have any alloy between the edges of 2 of the holes....

If you have the gear and knowhow I would weld em up, the forces on the centre of the wheel are quite massive.
