OEI, you need to factor in the loss of climb gradient in a turn and the very large turn radius for a small angle of bank. Good idea but generally doesn't cut the mustard.
If you can't clear the terrain, you have no choice but to circle. Just use the scenario of an airport in a bowl(or large cirque). You will be turning and able to climb or if, not....then descend.

Didn't work too well, for instance, at Mt Erebus ? OK, I'm being a tad facetious. However, the EGPWS terrain databases are not worldwide and, I suspect, not of sufficient accuracy to support OEI planning. Better than nothing, certainly.
Erebus was well before EGPWS map display of course, but the database is active for most of the places where most of us are flying to. Use what you got if you need it.
