Default Bogen CHB-35 to conversion to B-12/B-15

Basically, I'm wondering if this could be a good idea and any problems that might get in my way....

I have a Bogen CHB-35A I picked up at a thrift store and have messed around changing tone control, adding a grounded 3-wire plug, 1/4 jacks, etc. Looking at the schematic for the Ampeg B-12/B-15 it seems like it might work to convert the Bogen to a similar circuit. I love the sound of the old B-15's and it seems like it would be possible to wire up V1A/V1B of the Bogen like V1 of the Ampeg, and V2A/V2B like V3. I guess I would then just ditch the 6C4 tube? Would there be some other application for this? Am I crazy? I'm still very new to this... thanks!
