If you're up for something unique try this out:

8.5 hour shifts
6 days on
1 day off
5 days on
4 days off
repeat 16 day cycle

The first shift (call them A shift) comes in Monday say 8:00a to 4:30p. They wouldn't come in again until 9:30am Tuesday and would work until 6:00p. Basically they come in an hour and a half later each day. This way everyone works all parts of the day and it's easy to adjust when you're changing by 1.5 hours each day. A, B, and C shift would be like that. The fourth shift, D shift, would cover the 4 day blocks that the other shifts have off. With other shift schedules the D shift gets the weirdest schedule (like the crazy shift you mentioned) but here you can arrange it so that D shift works:
4 days on
1 day off
4 days on
1 day off
4 days on
2 days off
repeat 16 day cycle
And you can arrange it so that D shift works mostly during the day. For example they could cover when A shift would have worked 9:30a-6:00p, the next day 11:00a-7:30p, third day 12:30a-9:00p, and fourth day 2:00p-10:30p. Then D shift gets a day off and then cover when C shift would have worked first day 10:00a-6:30p, second day 11:30a-8:00p, 1:00p-9:30p, 2:30p-11:00p. Then D shift gets another day off and then cover for B shift very similar hours. This is good for D shift that the hours are mostly all during the day (easy to adjust) plus it lets A,B,C shifts have long 4 day breaks after they have adjusted to day shift again (their last shift before long break would been during the day so they can fully appreciate their time off). It’s actually tougher in a way for D shift’s sleep schedule, they should avoid getting up too late in the day during the end of the four day work week so they can wake up early in the day at the beginning of a new four day work week.
All of this is much easier to see in a spreadsheet but I can't paste it here, hopefully you can construct it.
With what I've said so far it looks like A,B,C are working 12 days and off 4 so you need some part time people to cover once for each shift after they've worked 6 days. The way my spreadsheet is set up every 16 days you would need a standby shift (E shift) to cover 12:00a-8:30a for A shift once, 12:30a-9:00a for B shift once, and 1:00a-9:30a for C shift once. These three times are equally spaced among the 16 days. When all is said and done A,B,C are all working an average of 41 hours per week, the sleep schedule is very reasonable, A,B,C get long 4 day breaks every 16 days. D shift gets to stay on mostly during the day. Downside is you need a few part time people to cover E shift 3 shifts every 16 days. Another downside is this schedule is complicated to explain without looking at a spreadsheet (color coded:) and it changes every day but repeats every 16 days.
