Luke II Adjustments as standard VS comfortable playing

I need your advices as you will know more than me for sure 🙂
I’m trying to set up my luke II following the standard specs (truss rod, string height) but I find it very hard to play it now. I’ve got now a perfect neck relief but as I said (on the 8th fret I’ve got 1mm), i find it hard in playing and the string tension is higher now.

What I ask now is, what If I set the guitar as I prefer (more comfortable for me, my hands – as other guitars I have) and not as the standard specs say? Do I risk to ruin my loved luke?

What I wish is to have a smooth and easy play with a warm sound. I would achieve it giving some extra neck relief and setting up all again (saddles , bridge…). Or, what else should I do for getting the same smooth and soft feel respecting the standard specs? (standard specs used in general for all electric guitar – I don’t personally know the Luke standard specs 🙁 )

Sorry for my “ignorance” I’m sure all of you pros, know what to suggest 🙂 Thank you in advance
