Moving on from a 2018 Altitude- Geometry questions

Unfortunately my 2018 RM altitude is coming to the end of her life, something that causes great suffering.

I think I'm set on staying full 27.5 which is somewhat limiting, but I think I'm committed to the Edit 27.5.

Maybe it's just because I'm so familiar with the bike over many years but I don't really want to stray to far from the size and geo of this frame.

Considering this, would you just get the Edit 27.5, or take a risk, get the MX and drop a 27.5 front fork/wheel in to steepen the head angle and seat tube up. (Is there any way to determine what the resulting geo numbers would be?) But I'm not sure if this would affect handling and BB drop in a negative way. Any thoughts or experiences welcomed.

Thanks
