8 lug to 5/6 lug

[79 blue monster]

my truck is a 3/4 ton thats static dropped. im having a very hard time finding wheels that are the correct offset, with, size. i lowered a 3/4ton because i wanted it to be unique rather than a 1/2 ton. since i cant find any wheels that i like(or fit), i was wondering if i can keep the 3/4 suspension but drill out the 8lug pattern to a 5 or 6 lug pattern. the only thing is, i dont know if a 5/6 lug pattern can fit over the center hub on a 3/4 ton axle. any help/opinions apreciated.
