should be alright for the most part depending on the type of 7g (L enter key version) and there MIGHT be a 7g that has the euro 6g layout out there.
problem keys:
euro: enter, left shift, left ctrl, left windows, left alt, spacebar. and a missing key (blank set's only 104) plus stabilizers on the bigger keys.
L enter type: just the backspace and enter. but there also might be the problem of different stabilizers on the 7g's spacebar, shift keys, some numpad keys.
color is a bit off too, filco blanks are darker.
although i'm reasonably sure that the key row profiles are similar to the filcos, i can't guarantee it.
