Not only is that a lot of money to pay for an 808 plugin, but don’t forget that once you own it you’re still going to be reliant on Roland Cloud for authorisation and all the fun potential issues that may arise from that - at the absolute minimum, it means keeping some unnecessary software installed just to use a plugin you own.
Alternatively, you could grab some 808 samples or something like Nepheton, or even Wave Alchemy’s Revolution (both of which frequently go on sale, the latter of which I would recommend in a heartbeat as a general go-to for classic drum machines in software form) - unless I’m misinterpreting, you’re replacing the drums anyway and seeing as you’re OK with an emulated compromise already… does it really matter if the sound isn’t super-duper authentic?
Tldr: I wouldn’t bother with the faff and price of Roland Cloud, I’d look at an alternative.
