Since you are experimenting, try mixing equal parts of BLO, MS or turpentine, and poly. You can add some japan drier if you like. It will give a similar look and feel as Danish oil, but will dry much faster and will be somewhat more durable. Apply with blue towels in very thin coats. The final coat can be sanded in using 600 grit wet/dry sandpaper to give a silky smooth final surface. Finish with a coat of paste wax.
I haven't tried it, but I understand a 50-50 mix of danish oil and poly does about the same.
