I doubt that you will find everything in one instrument. For starters standard UVVIS CCDs are Si and have 200-1000nm range (and edges are almost useless). For longer InGaAs CCD are used but they are more expensive, have lower response, more noise etc. What you can do is do just monochromator with 2 exits and appropriate photodiode on each and than scan spectrum via software (it just rotates grating stepwise and records).
-- For VIS it could be doable if your florescence is strong (typically you want to focus the excitation to maximize signal so different configuration from absorption that should be collimated). Simplest would be fiberoptic y probe with refection adapter at the end (look again at Thorlabs) but all depends on signal strength. If you make something similar yourself you can even put some polarizer in the sample's optical path.
Like I said, if you want to improve signal (and ambient light will be the problem) I would assume that you can pulse your led with a simple circuit and CCS detects at that particular frequency (need phase matching which is more complicated). In optics labs it is done with lock-in amplifiers but that is expensive.
