I looked at rewriting a canvas + loads of HTML, tables etc. game in Bevy with egui. Most of the things you mentioned were trivial, async RPC queries with callbacks, all of that worked fine out-of-the-box.
The sticky parts were where I needed more complex UI functionality. In the web world you can leverage mature, albeit heavy libraries for graphs and tables. In pure egui, you often need to roll your own and extend the basic features. Depending on how far you go down this road, it may make more sense to work within Bevy's UI entirely.
Dioxus looks like an interesting alternative here, but it also seems to be even heavier than egui, which isn't exactly a lite dependency.
