Absolutely! Just buy everything you desire and can afford. That's what you learn here. Only last week I was clearing a couple of boxes in a storage room at home and to my shame I discovered a hoard of pens I had bought a few years ago and totally forgotten - mostly user-grade but including a couple of gems, like a Mercedes that just needs a bit of nib work and a mint Pelikan 140. Now, which ink would suit a black semi-flex pen?
Well, I don't use Black ink, so the notion of matching ink colour to pen colour is out the window.
I'm still learning how to get the best from semi-flex nib, which slows my writing speed considerably. So I'd be writing a brief personal letter. That would have me choosing a somewhat vibrant ink that suits the shorter letter - not one of the more muted inks I use for tomes.
Considering the mood I'm in today, I'd be writing sunny Sunday happy thoughts, so Pilot kon-peki would be my inky pick: a pleasurable writing experience, reluctant to give railroading (tram lines) when the nib is flexed, and provides just enough shading to complement the modest line width variation from flexing the nib without becoming jumbled. Pen+ink also suits the few sheets of Rhodia stowed in my satchel.
Just add espresso & a sunny terrace . . .
