I am afraid this thread (like many others) will turn into a 'why not build a new accelerator card' type of thread.
However I cannot stop myself from asking this; Are you keeping some sort of diary on your progress? Do not get me wrong, I am not asking this to see when the card you are creating gets ready (I have an A500+ so it would not even be compatible I guess) but rather to know what needs to be done to actually go through a project like this one; what are the difficulties, how to solve them, the various tasks and so on. I think that would be an interesting read :-)
