2021 GC680 4motion with solar ... leisure battery question

I feel that my OE battery is getting a bit weak and I'm looking at replacements that will be a like for like replacement but more capacity. I tend to wild camp for 3-4 days then a day on a site but I'm driving (solo) most days anyway so I don't need much more.

Is there any reason I can't fit a 120Ah AGM leisure battery that can be discharged by 70%? That gives me 84Ah usable before solar?

everything else is too complex, too expensive, and unnecessary for someone who is happy to boil/fry/bbq and doesn't have a coffee/airfryer obsession.

It is recommended that AGM batteries should not be discharged below 50% capacity on a regular basis.
As far as a replacement leisure battery, you can fit any capacity battery as long as its physical dimensions allow.

This one claims 70% and is guaranteed for 5 years. Cheap enough to replace more frequently and definitely cheaper and easier than grafting on something more complex.
Of course, if I could squeeze 2 in there …..
