1) that the impedance of the driver is flat (and it is not) or at least the same value at the new crossover point (it is very unlikely).
2) that the driver response is relatively flat in the frequency range that the crossover is being moved (possible).
3) that the driver response (natural rolloff) wasn't used as an effective element in the crossover (also possible).
4) that the MF driver can handle the extra LF load (6dB/oct doesn't reduce the LF energy reaching the MF driver very quickly
as frequency gets lower ... if you don't play loudly, this might be ok).

But having said all that, it's easy to ignore all of that and try, if you don't mind pulling the 2mH inductor and 6uF cap from one of your L36s
(put the 2mH in series with the original, and put the 6uF in parallel with the original).
