There are several serious caveats that make such a conversion not really viable:

  1. The bandwidth would be very narrow. It will almost limit you to a single frequency on 160m without making a physical adjustment to the antenna every time you want to move frequency.
  2. The performance would be very low efficiency just like you would expect from a short 25 foot tall antenna on 160m.
  3. You would be totally eliminating your 80m band capability for poor low efficiency performance on 160m.

You would be far better off to install a more efficient temporary inverted "L" antenna type for 160m than do this conversion.
