OK, I'm having trouble following this thread. If your going to have two gyros
one electric and one vacuum, the cost of the vacuum pump + gyro is the close
to the price of a second electric. (Our your first)
If your going to be flying in glider mode you need electric gyros. Having
instrument that you inop during flight and tell yourself "well I'm not going
to use that in this mode" is not a good idea. In a moment of disorientation
you will glance at it because that is what you're trained to do.
If you look at this document: Page 69 (doc is 7.9 mb)

If Airmaster modifies Item 1, V-belt pulley, They could have their drum slip
rings and alt. drive belt pulley in one package.
>>I am considering adding to the back of the cowling to extend it forward for
the alternator.
The problem here is you run into the back of the prop before you clear the
Alt. pulleys. The installation I saw on tweety bird, alt pulleys were very
very close to the cowl. So you also need a prop extension.
>>so with vacuum gyros, the belt drive alternator is mandatory.
Why?
