An ELR greater than the DALR is so unstable as to be unlikely in real life, except at ground level.
Not the case at all, certainly in hot countries you will often find this happens and is how Cbs start, ELR greater than DALR so the air rises until it reaches the dewpoint at which point it forms the base of the cloud and then rises at the SALR and goes up even faster!
In fact you can even have an inversion - say 10C at the surface, 8 at 1,000' and at 2,000 it goes back to 10, as the day goes on the surface warms to 16C and so will rise at the DALR to 2,000' and is thus also at 10C, any further surface warming will thus cause it to break through the inversion and Cbs are extremely likely!
