Parts to convert TS 16v hydraulic to mechanical followers

Hi,
Are there existing parts to convert hydraulic followers into mechanical ones for TS 16v engines ?
We'd need a part to replace the adjustment system (finger), and we'd need a shim on the 7mm stem.

Something like on the picture below (taken from here)



Or did someone make the conversion by simply emptying the adjustment finger ?
According to my tests the shim would be in a 2-4mm range, which matches Maserati biturbo shims, but they are quite expensive.

Thanks

PS: I'm continuing investigation.
If the finger is emptied (so adjusted to max lash) and its back is pushed by the followers back the lash is 0.85mm . Not enough to insert a shim.

Thanks
Yeah these AHM 6mm one groove valves are nice. And EXPENSIVE ! 320 GBP for 16 guides is a joke
I've digged in more.
BMW e36 engines have hydraulic 33mm buckets (same diameter as in TS), possibly same dimensions but I've got to find one to check. References are FOL120 or HL6330, while TS use FOL106 or HL6335 buckets.
In M3 version BMW used top shim based buckets and I'm quite sure they would work in TS. But I don't like on-top shims, they are heavy, they sometimes escape from the bucket and you can not adjust them with sand paper so you have to have a kit which costs alot.
Lancia TS versions also had on-top shims but I don't know whether they were 33 or 35mm buckets. I'm quite sure Fiat 1.8 16v has 35 hydraulic buckets.
