Plenty of successful startups had money coming in from another source (see also: Microsoft) or piggy-backed off another company for a while (again: see Microsoft). It sounds like you could easily transition down to a 6-7 hour day and then later to a 4 hour day there, and be working hard for 7-8 hours a day on your other startup ideas.
Who knows? They say a change is as good as a holiday, and doing something different may also re-invigorate you to provide more energy back into the original business. I know I get better results when I have multiple jobs to think about than just one.
Working two jobs sounds too hard? Some people work three.
But I agree with the other commenter who said it sounds like mentally you've already 'checked out'. Go the whole hog for a while, and start treating it exactly like just a paycheck. You want to do other stuff? No one is stopping you, but you.
