Moving apps to a single unmirrored SSD. How to play safe?

Hi,

I have a simple system in a Jonsbo N2 case:
Intel J6413 with one vdev 5 wide 6TB HDD in RAIDZ1.
My apps are also installed on that spinning rust vdev , which is apparently somewhat of a beginner mistake that i made.
I want to move the apps to a SSD drive to speed things up, and prevent constant i/o on the HDDs and maybe allow them to spin down as there are days that i don't touch my storage at all (its just media/photos/documents backup).
The problem is: I only have space for a single additional SSD in my system.
I'm willing to take the risk that i lose 1-2 days of data on my apps and suffer some downtime if my drive fails, but i wanted to make sure that i can restore my apps if something goes wrong.

my plan was to move the apps to the single SSD.
run daily backups with heavyscript
1 hour after heavyscript backup run a replication task that replicate the ix-applications folder to my HDD storage pool (

If i do that, and my single SSD fails, can i just plug in a new SSD, replicate the ix-application dataset from my HDD storage pool to the new SSD, select the new SSD as app pool, and run the heavyscript backup restore?
Am i correct in my assumptions that this would be a relatively easy and safe way to make sure my apps are safe?

thanks!
