Why designing/making keyboards

I was regularly visiting Geekhack website in 2010 and at that time found my end game boards: a full size Filco Majestouch and a Topre Realforce.
I was very happy with those boards and didn't see a need to spend further money and energy looking for replacements, so forgot about this great website and worked/played happily with what I had purchased.

When I (coincidentally) visited Geekhack website again in 2018, I was shocked at the progress this hobby made in 8 years:

• A myriad of MX switches choices, before we only had the choice of Black/Blue/Brown variants and Reds were available only on the asian market.

• Lots of people designing and selling gorgeous full metal keyboards.

I badly wanted to type on one those nice boards but refrained from compulsively spend my money in one (or more) of those GB projects.
What if I was designing a keyboard myself ?
Could I be capable of doing such thing ?
The only way to know for sure it is to try, this is when my first keyboard project started.
