You could trade-in Akamatsu sure, but Trade-In MU for MU is an issue if this ends installing Akamatsu for nothing. You should find another hardware that you want in multiple in your deck (R&D-I and HQ-I for exemple).
Draw-Draw, install Aka, Trade-In, Install desperado cost 5 clic and 5c, with a MU -1 +1 effect.
Draw-Draw, install PPVP, Trade-In, Install Desperado cost 5 clic and 3c (Trade-In refunds 1c, and recurring cred on PPVP buy you the event)
In one case you have +3 clic +2c cost in half of your game, in the other in you only have +3 clics in half of the games.
Now, my reasoning behind that is if you play Shaper, you can compress draw enough to make that clic loss practically a non-issue (+ a 3-turn PPVP can buy you the Despe in theory).
It is all about clic compression there and imo, Temujin Despe Trade-In is more Kate stuff (where draw compression clog hand), and less Smoke.
If you still try that, you may want to pack Analog Dreamer in those decks (I’m considering it seriously if I replace Multitheader to find more inf, replacing a Lucky by a Day Job as a meh solution, and trying to get another 3rd inf somewhere, is my Parasite).
Also, Personnal Workshop is a Shaper card.
