Sound like a case of modeller and FRFR to me. It makes sense - you can get a FRFR that can point at your head like a wedge... and any tonal inaccuracies that you don't like, you can tweak out at the model. EQ, more grit/less grit, etc...etc... Modellers are so good now, it's a route that you'd be foolish to not look into. With an amp and cab, you have preset sounds backed in... that are very difficult to remove or influence. As you've experienced, the EBS has quite a hyped top end - thats largely due to their use of the Selenium tweeter and the crossover point that EBS implement. I actually think it's sound very, very musical, especially with the EBS amps. Maybe the problem in the top end lies with the amp and not the cabinet?
I use a Kemper but generally only use it for one sound - but the profile that I am using on it is perfect for what I am looking for.
I'm intrigued as to why you are against inears. If you run a decent set of inears - and I'm not talking Shure 215s, then there's a whole revelation waiting for you. I've spent as much on my inears as my powered Kemper and remote - and it's by far the best sound I've had on stage ever. Massive lows, incredible detail... and the added benefit of not going more deaf after every gig.
