FWIW, it is usually easiest to empty out and stabilize a kayak for re-entry by someone in another kayak. You can mix boat types and still have it work, but it takes more practice to get that down than working from two kayaks with dual bulkheads (or equivalent effect with bow and stern bags in terms of water displacement).
I would suggest that you keep an eye out for a buddy who also has a kayak with decent flotation at each end, then mess with assisted rescues on a nice hot day after watching videos.
To get a sense of how easy this can be if everyone is properly equipped, boats and skills, the typical assessment standard is to hit 2 minutes or less from capsize to the paddler back in an emptied kayak and with skirt on. Having one higher sided boat can complicate things in unexpected ways. They are perfectly solvable - but typically take more practice to get down.
