What if the software has an almost identical UI?
It doesn't matter if you can't simply import Revit projects into it and work as usual. That is how Excel got its foothold into the spreadsheet market dominated by Lotus 123 at the time, you need to support the current de facto file standard for that industry/task.
There's also the plugin ecosystem to consider - ranging from small things you might have self-written or exchanged with other users over the years for your workflows or to add missing functionality [1], to complete commercial add-on packages adding big chunks of domain-specific functionality.
[1] Some of which frankly should just be built-in, but either way it wouldn't make creating a replacement any easier.

Revit / AutoCAD import / export is sine qua non - everyone in this space is going to offer it before going to market.

Trust me - you never want to work on a job where the new owner wants Issue For Construction in Bently Microstation and you have 10, 000 Autocad files from 30% initial engineering. It's not fun.
Productivity lost by adopting new tools would render firm non-competitive in this thin margin business, will likely make your P/L red.
