Suppose you get four offers, two for Pharmacy and two for Radiography. How would you decide which to firm and which to insure? You'd have to do so by June next year. What information will you have then, which you don't have now, that would allow you to choose which course to pursue?
The more likely scenario is that you'd get fewer than four offers because your personal statement does not convey a passion for the subject for which you'd be applying.
Whilst you could pursue this approach, it would not be wise.
