Why not ?
the sensors can detect light from UV to IR, the point of modifying them is to "enhance" the red end of their response.
I still see no real need to mod my 40D BTW, it's used more for happy snaps and general photography than astro stuff and I am not impressed with the results people get with the "fix" they apply to their modded DSLRs to use them in general photography .... modding is more bother than it's worth in my opinion.
There is no reason why narrow band Ha ,OIII and SII photography wont be successful with a DSLR , and it need not be a modded DSLR either. It's just a matter of using appropriate exposures for the camera's sensitivity in that band.
