I agree with the idea that the basic principles of voicing are the same for any hammer. Probably the most important is laying the foundation so that each hammer is focused on its strings. That means starting with meticulous travel and hammer squaring (vertical on its shank, in line with the arc of travel of the shank), so that the hammer moves directly vertically, no wobble (firm pinning is a prerequisite for this). Then level strings and file hammers so that their profile is correct and so that the crowns are perfectly square to the vertical travel of the shank. Touch up mating as needed.
No shortcuts. Simply do it as a matter of course. Until you have done this work, any "voicing" you do is lipstick on a pig, because you haven't addressed what is fundamentally important: unison strings that are impacted simultaneously. If there isn't simultaneity, there will be out of phase vibrations, and they will be chaotic, varying from unison to unison and within a unison depending on the strength of the blow. There will also be extraneous tonal components, including nasal sounds, zingy sounds, dead sounds, etc.
Once this foundation is laid, you have focus of tone and can proceed to needle, in order to expand the range of timbre.. In my experience, deep shoulder needling is essential (in softer pressed hammers as well as harder pressed). I prefer the pattern of needle insertion depicted in the attached photo, which is somewhat unconventional but has worked very well for me in hundreds of sets of hammers. The lines are 10 mm long. That is generally my minimum needle length for most of the piano (I often use 11 - 12 mm), tapering in the the top three octaves.
Conventional diagrams show needles inserted radially, aimed from the surface directly to the core. I find that pattern is impossible to achieve more often than not, particularly with denser hammers. You are trying to penetrate an ever increasing density of felt fibers. When you start at the mid shoulder and aim to penetrate more or less parallel to the outer surface of the felt insertion is far easier. The first insertion opens up the outer felt, providing space for the next, parallel insertion - somewhere for the felt to go, and this is progressive. (If the felt is too dense for this, I use two needles instead of three, making two side by side lines up the surface of the hammer. In extreme cases I use one needle).
Moving up the shoulder toward the crown, the angle is changed gradually, until at the very top it is aimed outward, leaving a pointed area of felt above the tip of the molding untouched. The pattern of opening the felt is the same as in most conventional drawings, but is achieved differently and more easily.
I simply do this pattern to every hammer, whether lacquered or not. The results are a broad range of timbral color that will need minimal touch up to even things out. Most of the touch up is quite near the middle of the crown.

On the proximal side, yes.

Did you find you had to work pretty hard to get the needles in these at first? I had to start shallow and work my way in a bit.
