ZFS is fine with external disks and indirect access to hardware in my limited experience. Performance would not be as optimal as it could be but data integrity shouldn't be a problem. If I didn't need the space and this was my primary storage array, I'd probably opt for the increased reliability of 2 mirror vdevs. I've done something similar to what OP is suggesting with LVM combining multiple disks on my off-site backup though. I combined 1T+3T+4T disks into a single 8TB volume. Deliciously bastardized, not a single integrity issue, no hardware failures either over the several years it ran.
Cool. Yeah, as a professional I am constantly aware of data integrity and have most of my shit stored on redundant drives. I had a WoW Guild Officer who shared his home setup with like 8x12TB drives in Windows Storage Spaces with no redundancy that was like 80% full. I had to ask how he slept at night knowing he could lose 80TB of data at any time.
Personally my TrueNAS has 5x1.92TB SSDs setup in two mirror vdevs and a hot spare for my ISCSI LUNs and 8x1.2TB 10K drives in a raidz2 (2 disk parity) for my NAS storage.
