I think let Banjo be Banjo and let Playtonic be Playtonic.
I'm not even clamoring for Rare to make a new Banjo game, can we PLEASE get some new games going in 2015+ that rival the old great franchises? New, new, new. Thanks!!
...That being said, I do hope Ptonic get "rich & successfull enuff to just out right buy banjokazooies IP", I just hope they do something else with their money.
