Hi Andrew,
if you do not mind if your output looks a bit funny, you may replace any 
subscripted variable by a symbol whose name is constructed by the 
original name and the index. E.g.

Unprotect[Subscript];
Subscript[x1_,x2_]:=Symbol[ToString[x1]<>"sub"<>ToString[x2]]

This will change any subcsripted variable into a symbol with name ...sub...
