I think you will find it difficult to get a new HT-receiver that sounds "as good" as a similarly-priced two-channel integrated on two-channel, generally, and in a vacuum.
The HT-receiver(s) will probably have loads more features and toys that might make the difference for you--bass management, room correction, etc.--especially on your digital stuff, and depending on what other gear you are using.
If you don't need stuff like Atmos, DTS-X, 45 surround and subwoofer channels, 4k conversion or video processing, maybe take a look at a used HT-receiver that was several "levels" up in its day. Maybe you will find a middle ground that gets you some of the flexibility and features you want but with "better" two-channel or at least "better" amplification.
Just a suggestion to think about.
