Can't get a Committee Letter. Will Letter Packets be enough or will I get rejected for not having a Committee Letter ?

Long story short, my school requires a 3.3 sgpa for 2 years in order to get a committe letter, however my sgpa was in the 2.8 range for a while until I got my act together and got an upward trend in the last 1.5 years and got my sgpa up to a 3.35 (overall to a 3.53). My MCAT is decent enough for me to apply (514) and my ECs are pretty good (as well as my letter of recs) but I'm kind of scared that my low sgpa along with the lack of committee letter will get me rejected from most MD/DO...
