You can try combining the cages when everyone is neutered and healed. You can also place both cages in one room as long as you cover and observe the gliders while out You could place mesh type screen over the front of the cage making sure they can not get to the edges of the screen to avoid issues.
Stsrt swapping cage items like blankets,toys,pouches that are scented now and in a few weeks even switch cages. This way everyone is familiar with each others scents. When you introduce them do it in a dry bathtub or tent this way it is a neutral spot and you can grab them if needed easily. After they are introduced I place them into a travel cage to sleep for the day making sure no issues break out. At night I add them to a fresh clean cage with lots of new things to play with and several feed dishes. In your cage like 3-4 feed dishes.
Good Luck and let us know how it goes.
