Shade Gardening: Help me plan my plantings for this corner shade garden, 1 by rouge21

The last couple of weeks I came down with year end 'garden fever' ;) and so for 'treatment' I proceeded to do some of the basic work starting a new corner garden by expropriating some backyard lawn. This quarter circle is about 130 square feet and experiences very much shade. As well future plants will have to contend with competition from neighbouring trees (see picture below).

And although I have never been bitten by the hosta bug I think with all this shade I feel I need to revisit this plant.

After lots of web browsing I am intrigued by what I have seen of the "Liberty" hosta. It looks like the hosta for non-hosta lovers? A very impressive plant.

And so to this end I was thinking of planting 3 equally spaced "Liberty" on the front border arc with some all season flowering plant in between. (I would have liked this to be a shade impatiens but I will force myself to not select this plant given my experience with "downy mildew" this past summer.)

In the very back corner I am thinking of putting a single Eleutherococcus [Acanthopanax] sieboldianus 'Variegatus' shrub.

After the front and very back accounted for I think there still would be room for something in between.....maybe an arc of some "Ligularia"?

Of course I would love to hear your recommendations re plant possibilities and arrangement for this area.
