Hopefully there is a way to upgrade the latest Mk2 ES to the new MR version.  Haven't seen any reviews on the new MR though.

I just asked Peter that question and he responded yesterday, on a Holiday no less. He does make a Current Mode version of the Hyperion but he prefers the Voltage Mode version. When I had the Voice I was using an AR phono stage. My Seta L Plus has both TI and Voltage operation, switchable on the front panel. The loading switches for Voltage Mode are on the back panel.

You sure can. The coils and magnets are identical. A rebuild replaces everything that moves. I do not think there will be much of a change. The Hyperion already has an excellent stylus. The micro ridge stylus might track very high frequencies better, but we can't hear that high. 

One wonders what the inductance of a low output MI might be, to render it useable with current driven phono stages. Very interesting.

I was wondering that also but I did not feel like bothering him asking for the specifics. He thinks the voltage mode works better so I went with that.

I’m thinking if you reduce the voltage output significantly, so that fewer turns of wire are needed to generate the lower signal voltage (and also resulting in a lower internal R and inductance), then it might be possible to mate the Hyperion to a current driven phono, but as you reduce voltage out, you need to hope for a greater loss of internal R and inductance, so as to get a net increase in current output at audio frequencies. You did the right thing; just use conventional voltage drive.
