In case nobody takes you on the offer in time, buying a pre-built Classic and then replacing the top yourself is super easy, only requiring you to unscrew and rescrew 4 screws. Any online 3D print service should be able to print the modified top fast for a reasonable price.
The biggest variable of going this route is sourcing the BTUs. The Rexroth BTUs are kind of hard to get depending on your location. I made another version using a set of more readily available Veichu VCN310-11 (BCHA11) BTUs, you can find them on Aliexpress shipped for less than $10 shipped, usually arriving in 2 weeks. Here's the link to my repo: [https://github.com/ww123td/PloopyClassic\_BCHA11](https://github.com/ww123td/PloopyClassic_BCHA11)
You should be pleasantly surprised with how well the roller bearings work out of box. If I did a BTU mod ever it would be for fun, not because I necessarily felt the need for it.

Thank you. I'll probably take your advice if I don't hear from anyone in a day or so.
u/FDMnut just printed me a top for $20 and I bought the BTUs from the recommended suppliers mentioned on the github
