Here's what I did once during a scape change/substrate swap..
Put all the fish in a large bucket with tank water.. put an airstone in there, and ran my filters the whole time in the bucket as to not kill the BB. Then I swapped the substrate, added water/prime, put fish back in.. then hooked up the filters and etc.. done.
In your case I suggest doing the same. Take out the fish, keep filters running in a bucket, do you rescape/swap, add water and filters and fish again.
Aquasoil leeches ammonium, so you're probably gonna have a mini cycle going on. Do large water changes a few times a week and your should be set in a few weeks.
I'm sure you should be okay doing that. Also, make sure you heavily plant.
Most water quality issues can be fixed by doing a WC!
