I had to watch a really boring "entertainment" program and used that time to edit the above file into a working C++ program. Echo was never used. Due to the peculiar permutation order Blake and Bmw are always fixed at position 0 and 1 respectively, only the remaining 8 positions change. So using the terminology from the whitefire990's post above timetravel10 requires only 9 reconfigurable blocks assuming that only Groestl requires a double block.
This is very interesting. I did some math and there is a very decent chance Bitcore would fit in a VU9P (while for sure it fits in a more expensive VU13P).
