Flash Power Supplies Answered

I don't have a lot of money to spend on stuff at the moment. What I do have is flash guns. Four of them in fact, three of which can be fired with triggers. Now I could invest in 16 rechargeable batteries. Or should that be 32 in case I run out? And a crap load of chargers.  And extensions cos we have no spare sockets in our house. But that just doesn't seem right to me.  

Heres what I propose :
1) make some dummy batteries from wood with wire running through the middle.   Three of these go in each flash to carry the connections 
2) a fourth dummy battery carries wires out of a small notch in the battery flap door
3) said wires are connected in parallel to a large rechargeable battery - I reckon a 6v from an old British motorcycle (fast draining) or from a granny wagon (deep cycle) should do the trick. 
4) when I'm done shooting I charge this single battery from the mains charger I have (does 6/12v)

I figure 4xAA batteries at 1.5v = a 6v battery, bu extra size should last longer, be more convenient than carrying around dozens of AAs and changing them and if I want to use AAs when our and about I still can  

Any reasons tho wouldn't work or I shouldn't do it?

Many people have done this instead of buying a commercial battery pack. It works quite well. You just have to make sure you don't damage the flash by firing it too quickly.
