Audio Technica AT-ART1000X

For overall sonics, the entire audio chain matters.  Usually to best lift Sonics, it’s best to address the weak link.  If one purchases a component significantly above the level of their audio chain, they will not realize the full potential of the component.  It’s best to strive for a balanced audio chain when lifting sonics.

My phono preamp is a Lejonklou Entity using Linn interconnects, Halo Serene preamp, Atmasphere D Class amp, Devore Obaby speakers, full Carda Clear loom

The OP asks whether the match is "crazy". It's not crazy. The downstream components noted above are good enough to "hear" what the cartridge is doing and maybe stimulate some other upgrades. 

For those of us who believe the source is the most important part of the chain (probably a debate we need not have in this thread), I cannot say it is crazy at all.

I have heard, and really liked, the ART 1000 cartridge.  I don't know if buying it will optimize your system performance in terms of bang for the buck, but I don't think your money would be wasted--you should be able to hear what that cartridge can do.
