I'm pretty sure you will find it harder to get a set of colour-printing filters than a colour enlarger. And you will probably pay more for them than a colour enlarger. And while they might work, they don't give you adjustments as fine as the knobs on colour enlarger (2 points matters!), and they're way more hassle than turning a knob.

The final insult is that gel filters (that go in the drawer) will fade over time and with use because they are merely dyes in a resin. In comparison, dichroic filters in a colour enlarger will never fade because they use metallic coatings on glass to achieve the filtering effect. A dichroic filter's effect is based on destructive interference of internal reflections in the coating layer - just like an anti-reflective coating, but of a thickness chosen to give strong attenuation of transmitted light at particular wavelengths.

Buy a real colour enlarger and don't make life unnecessarily difficult for yourself. It won't cost any more and it will save you grief and time.
