If the cloudbase is too low for an OHJ, then perhaps it is too low to be doing any sort of practical VFR flying... so whether or not to do an OHJ would be the least of your concerns.
Most of the local GA airfields around my neck of the woods are 2000' QFE for OHJ. If the cloudbase is <2000' AAL & >3/8 then you can't go very far, lots of ground >1500'-2000'
So for me it wouldn't be very sensible to go anywhere.
I agree with bjornhall's sentiments.
