Hence I think you have, regrettably, answered your own question.
Its all very well having a vision, but executing it is a different question.
The sort of thing you propose requires a lot of time and a lot of money to develop. Let alone maintain. Let alone market and sell.
Look, its like all those "Bloomberg killers" that come out of the woodwork as often as the seasons in the financial world. There is a reason why only Bloomberg and Reuters are at the top tier, why the second tier is so narrow and why everything else is junk. To replicate Bloomberg would take years in time and billions in cash.
I admire your ambition, but perhaps rein it in a little ?
