Check out the Training Simulator:
(229484.1). It will give you some idea of what's possible.
I would suggest you do pressure (PG) to get your 6'8" guys until your 18yo hits 10-11 OD, do a little 1v1F until your 19yo hits 6-7 HA, and then go whole hog into inside skills. You'll end up with a great LI SF and PF. And your C will be effective, too.
The height of the guard you want to draft is incompatible with the other guys you're training. I would say either sell him right away for a good sum, or work him into the Pressure (in place of the 19yo C) and 1v1F training to round him out into a PG/combo and then sell him.
