i have seen (with my own eyes) 5x144.3 redrilled to 4x100 - and it scared me. i'm a mechanical engineer, and i did not like the proximity of the holes to eachother.
welding up the holes and total redrilling would work, but you'd want it done properly, not bodgily.
i got a quote just for the redrilling from a proper, good machinist, for $40/wheel. thats a good price. but to weld up all the holes in aluminium, i would expect a lot more.
unless ofcourse you only want them for show, not to drive on
