At some point, I became obsessed by having an actual arrow cluster in a sixty layout, I found that giving up the right shift is an inferior solution as it makes touch typing pretty awkward, unless you do not touch type, in such case, layout does not matter, at all. Hunt and peck typing gives you a great deal of flexibility, layout wise.
I found the space bar alternative to be a superior solution to forcing an arrow cluster within the limits of a sixty keyboard, besides, it allows the use of some elegant layouts, like the HHKB style.
A similar layout can be achieved with this PCB. Although the main focus is a split-spacebar PCB. Here's an image of what is achievable similar to your layout.
