Whatever, please heed all the good advice over chainsaw safety.
A tower scaffold might be useful as a safe working platform if you can get
it close enough to the trees.
This would enable you to tackle the higher branches more easily.

Yes, I've done that, but it does have one serious factor to take into
consideration - there's no 'easy escape route' which is one of the
things you should always look for when felling. As long as nothing
you cut off while on the platform is big enough to hurt you seriously
then you should be OK. However don't cut really heavy stuff when on
the platform, if it falls in an unexpected direction you have nowhere
to go.
