A try on how a fast start for a 6 product solve might look like. Sadly, the second rebonding phase would not be straight forward as I first thought. I have a plan, on how to do the first rebonding a bit slower with a more favourable pattern for the second step, but didn't want to take the time to try it out.
(Also all those triplex bonds should only be done after the second rebonding phase, to do everything in parallel.
Structure of such a solve:
1. Grab all 6 inputs, meanwhile do the duplications.
2. Rebond the tips to good positions, such that all bonds can have supports while being changed from normal to triplex.
3. Rebond to get the original shape back, now with the inaccessible triplex bonds already formed.
4. Change the remaining bonds to triplex bonds and finish the triplex bonds up (so add the other two colours).
5. Calcify and remove unnecessary bonds and output.
