Qemu can run SPARC binaries and emulate a full SPARC system enough to run Solaris 2.6. Qemu can emulate Loongarch as well!
I know, but I would love to have it transparently, similar to some IOCCC guy that wrote a userland emulator to run Unix V4-v7 and up to BSD 2.1 binaries seamlessly. Similar to FreeBSD and NetBSD's compat(8) approach.
So you want CPU emul and a kernel personality. Kind of a tall ask, especially since you'll need much of Solaris anyway to run those vintage binaries.

X11 calls can be just forwarded to the currently running server in your machine. The rest, yes, it must be implemented.
PD: I'm not saying IE for Unix would run under that; Solaris it's pretty much post BSD 2.1 and maybe from another Unix branch.
But code from NetBSD could be adapted for such task.
We have:
* illumos
* binfmt (Assuming a Linux host)
* qemu
I'm not saying it's zero work, but this looks entirely solvable.
