Well, 60 days for delivery. Really?
That's not an issue at all, I offered a donation of a similar programmer to @zyssai if he wishes to try it. I have a few programming kits and I haven't used either of them in years. I would be very glad to pass it on to someone who will use it more.
I do believe that using the right tools yields better results in shorter time, than hacking the way to make one prototype work, and then have troubles making it repeatable in any way.
The voltage converter board, yes, I guess that would work. It's worth mentioning it has quite a limited speed, as it relies on pull-ups on the "output" side in either direction. To put that into perspective, SPI is faster than I2C exactly because SPI outputs have totem pole drivers.
In this application it would work, because the programming speed can be lowered. But it's worth remembering these simple level shifters are not an universal solution.
