Is it right of me to incorporate some Islamic practices into my life before making the conversion to Islam?

Sister, I had the same exact questions before I reverted. I thought I wanted to be a Muslim for 5 months before I reverted, but my brain still made me skeptical a bit. My advice is to go at your own pace. If you force yourself into something before YOU are ready to do it to please Allah (SWT) then you'll resent the act and in turn resent Islam. It'll feel oppressive rather than freeing. If you aren't ready to be labelled as a Muslim, then be a theist for now and slowly adopt Islamic changes. Allah knows your intentions. Only Allah can judge them. If you need any help or advice, you can contact me. I'm a new revert, so I'm learning myself. But I know what you're going through. Also, I was a hijabi before my Shahada. So the order you do things is totally individual.
