I dont know if this will help your situation or not but on the ones I have done with different wheel like you are using there is room to trim the wheel down where the sproket bolts on to get the sproket closer to the tire...Make sure to leave the center part that goes through the sproket for support and to keep it centered.... Then use an offset front sproket... Some of the rear sprokets are offset as well and you can flip them over to get it closer to the tire.... Make sure you leave enough room betwee the chain and tire though.... A lot of that you probably already know but I threw it in there anyway.....lol....

And if I don't belong...Who would have guessed it
