For potential future interest in this post from other users I just wanted to update everyone: I managed to complete the conversion successfully.
I installed a DT Swiss F232 Remote in the front, and a R232one Remote 210x55 with the bikeyoke on the back: for this last one the shop tech left the globe bushing in the upper eyelet, and added DT spacers/ferrules that filled the space in the frame for the shock installation, while straight DU bushings were necessary in the lower eyelet to avoid excessive freedom of movement. For this the shop managed to fabricate them appositely with a lathe, rather than ordering and waiting delivery (I was a bit in a hurry to get the bike back for racing events).
The feel with the bike has changed quite a bit: in locked mode the suspensions are super firm, eventually not granitic as a hard tail can be but I can now clearly feel how much of the "plushy-ness" is coming from the tyre pressure. I'd probably go for it for any tarmac of super smooth climb.
The pedaling mode is the one that reminds me more of the brain off-road, still with some differences/nuances. I like the current configuration more when climbing seated at regular pace as the platform feels very solid and efficient, still nicely compliant. I don't feel any bobbing and no unpleasant roughness or bump, and I obviously never feel the brain opening/closing. When standing and pushing, or in case of sudden spints/accelerations, or when I need to overcome a techy section maybe helping with the whole body the brain probably felt a bit more reactive. One can probably get around this by switchin to Close whenever more support is needed and back to Pedal afterwards, but to be clear: to me that's really nitpicking of minor nuances, and secondly I believe that this would just be for personal preference as I'm convinced there's no absolute speed/efficiency gain to be gotten here.
The open mode is the one where I feel the most evident changes: as I open the suspension the bike becomes immediately much "softer", giving the feel that it would eat anything you throw on its way. Somewhere here on the forum I read that the brain felt like a reduced travel suspension. I don't know if I feel like I have longer travel now: I'm not really convinced that the bike became more capable, and I still need to actively drive and absorb roughness during the descents, but all in all I'm now I'm more confident, more relaxed and less fatigued at the end, which turned out in better times on same segments I've been riding for years (both in races, or in trainings or easy rides).
The bike lost 0.3-0.4kg (0,6-0,9 lbs).
