I've read the papers by the guy who did the Al/LOX gel experiments.
That sucker is crazy, and blessed with incredible luck. There's no
clear indication of why the samples didn't explode (these were
quartz tubes filled with Al powder, and LOX added remotely).
Now, molten aluminum (with a bit of sodium or magnesium alloyed to
lower the melting point and improve ignition) should be hypergolic
with LOX. A preheated injector face and an ablative chamber should
work pretty well...
