Yes, lots of people over on r/telescopes or r/atming have done this and can give detailed answers if you actually plan on doing it. You can order premade lenses or mirrors to the specs needed and assemble it (or grind the optics yourself if you really want to DIY it).

Also keep in mind there are [several different types of telescopes](https://sas-sky.org/wp-content/uploads/2011/09/SAS-Types-of-Telescopes.pdf) with pros and cons for each type.
