I don't think that an entire re-do for a second BA/BS degree is needed. If you have retaken all your F/D/C science courses, then your GPA for DO schools will be much higher (you should recalculate your GPAs as per AACOMAS). Ditto that for SMP.
The 26 MCAT is more of an issue. For MD schools you need to do much better (513+)
In short, for DO schools, it will be worth applying this coming cycle. For MD schools, I think retaking the MCAT, doing better and doing as you're doing now for this Spring should be OK for those MD schools that reward reinvention (at end of Dec '16, send updates to those schools that accept them).
