I think you will be right.
The DA50mm 1.8 is a remnant from the K-50 past, and part of me wants to know that if the K-1 paired with a 'proper' full frame lens will produce a better shot. Silly I know, but I think I have to tick this off.
I struggle to get shots at 1.8-2 with the DA50mm, let alone 1.4, but I do want to persevere and get better, eventually doing portraits for people etc. Nothing better than a 1.4 headshot when done right! With the DA 1.8 I can't even get that choice.
Still... I should be able to sell the DA50mm for $100 or so, making the cost of the FA 50mm 1.4 come down in my mind somewhat
