Re: Alternative solution
"Our iTunes sales are about 3x our Google Play sales"
Looks like it's obvious which one to prioritise then.
You can't demand a platform changes to converge with another platform just because it would be convenient for you.
Apple won't allow web-apps for two reasons:
1. Poor user experience with battery drain etc.
2. Circumvent the App Store vetting and, of course, 30% cut.
The very reason iOS is so popular is that it's a closed system with more end user protection, and longer term support for OS updates, and more vetting of app behaviour. From the very start iOS has protected from battery drainage and other bad app behaviour.
Apple isn't going to throw that away to help cross platform development, which might also help Android device sales, taking away from iPad/iPhone sales. No way.
