I recommend taking them out and replacing with a Caragana 'Sutherland'. This tree has a nice form, but is shorter and narrower than most. It will still provide a vertical element in the bed, but not block the view. It is also a drought-tolerant prairie tree and has yellow flowers in spring and interesting bark in winter.
The shrub on the right could also be taken out and replaced with a low-growing juniper such as 'Andorra' or 'Green Carpet'.
