Yes, you can do it. I converted my DW5000s from chain to strap. I got tired of getting all the grease on my my clothes. I called DW and ordered a conversion kit, which they shipped to Guitar Center. I assume Tama will do the same for you.
No I mean like the axis or trick pedals that have that direct drive piece, you would think it is less expensive to make a pedal with a direct rod than with a chain.
...and about gimping Tama hi-hat stands. You mentioned it was reversible, how do you remove the leg and place it back on if the hinge is riveted...and there is no way of removing the bottom collar because the spring tension adjustion lever it in the way, and incorporated into the whole hi-hat base assembly...BTW it's a Roadpro model.
