I am only one voice but I would advise against a remaster - unless there is something you consider really terrible and blemishing the project. These games are long term projects, and your skill will always move on while you make it, and the technology, both hardware and software, also gets better. You may easily get stuck in a neverending circle, have seen that before.
Also I have the feeling - but cannot prove it - that remastering lends itself to graphics becoming more generic. With all the work of post production in this game the risk may be lower than usual, but there seems to be this tendency to move the sliders ever so little - but all towards the same spot. Which may be dictated by your general preferences or by some kind of trend going on, with changing tastes, however in my very subjective experience, it tends towards looks being more same-ish, losing their uniqueness.
But in the end, this is your game, your project, do what you feel is correct, not what people tell you - because then it will become really messy really quickly
