For me, no; but in terms of reducing the transfer time between the two stations, building them back where they were 50-odd years ago is probably the best you could hope for.
Again, the question nobody seems to be able to answer: how many people interchange between stations at Bradford? And, more importantly, how many would do so that don't currently if it was easier? Perhaps more pertinently for the various suggestions: 'How much revenue is the railway missing out on because of the lack of interchange?' If you know the railway is missing out on £x a year, then you know what your budget for improvements will be.
For the people who are making the change already, there is no revenue being missed.
For people who would travel via alternative means regardless, there is no revenue being missed.
For the people who travel, but to different destinations or not as far and switching to another option (taxi/bus), there is a fraction fare being missed.
For the people who choose not to travel by rail at all but would if the interchange was easier, there is a full fare being missed.
The price of a Halifax to Shipley anytime return is £6.50. Are you honestly saying that moving the station over the road will facilitate hundreds or thousands more journeys per day to cover some of the cost and stimulate enough economic activity for the tax income to cover the rest?
