I agree with your vision. A two night hang with picnic tables, toilets, and fire rings, then the choice of two hikes.

Option 1:

Kelly Dahl for the hang. Choice of Indian Peaks north loop or hike into Diamond Lake.

Option 2:

Turquoise Lake hang. Choice of north or south on Colorado Trail. South give the Mt. Massive option.

It can be done.
