Looks like a no from me, looking at travel prices:
Edinburgh to Leeds : £95
Edinburgh to York: £65
Flybe Edinburgh to Leeds Bradford: £196
National Express to Leeds coach station: £30 bit arrive at 6pm and leave at 8am next day. Also jot sure if that's 30 each way :s
Drive: £80 petrol + several gallons of oil...
You could walk.
Walking = free. 'Though you may have to fuel up on star bars to keep you going, so there /is/ a minimal cost. But you could make each one more energy filled by using your charm to get them deep fried for free at local chippies.
Start now, and document the whole journey in a diary style to keep us entertained between now and the meat.
