Lunar Lander for SLS

... and two, the Constellation program was centered around re-usability; meaning that, the lander couldn't be a several stage system.

No it wasn't. It was an expendable two-stage design, just like Apollo.

granted it is cool but the cooler tech was/is ATHLETE... which is a robotic base building robot

I still think NASA should invest in a LEO fuel Depot and a series of DEDICATED space tugs, preferably powered by NERVA engines... one can dream right?

Yes as I understand it also did orbital injection,

This who Woopert posted is an reuseable lander.

And yes it look a bit kerbal, probably because of the fuel tank and legs. Think I have seen the cabin as a mod.
