The way things have been going for LD it'll be the 5 mana with 8 mana for overload but it will blow yours up as well.
I agree. If such an Overloadable land destruction spell gets printed, it's going to be either "target land" (so it destroys all lands including yours when Overloaded) or "target non-basic land you don't control".

Destroy target land you don't control
Overload 4RRR
Or a cheaper Overload to affect all lands. The mechanic calls for a spell like this too much to pass up.
In essence, it'll be just the spell to push red back into land destruction as a viable option
I doubt Wizards will print an Overload LD spell, although it would be very cool to attempt to make it constructed playable.
