Can a modern IFR Instrument Panel be as SMALL as a glider instrument panel?

[Bearcat F8F]

Hi guys,

I am thinking of designing a glider, which can be transformed (relatively easily) into a personal jet aircraft. This is a university project (for now).

I would like to take a typical glider fuselage as a base to work with. Hence, I'm wondering if it's possible to create a relatively small glass cockpit that can be used for normal glider flying, but also for IFR flying when the a/c is converted into a jet? I'm guessing something like the G1000 is a bit big to fit into a normal glider panel.

I could move the pilot further back, creating a larger instrument panel. But should I?

Thanks
