Mixing

In the absurdist play Rosencrantz and Guildenstern are Dead, the two main characters Rosencrantz and Guildenstern(or are they?) are always mixing up which of them is who—or sometimes which of their own body parts is which—because of a perceived lack of individual identity. Wouldn't it be absurd if they even shuffled around their names?
Your task it to write a function which takes in a string of an even length(and by design, a multiple of 4) that is greater than 7 characters, split it, and shuffle it.
The splitting shall be as follows:
the string will be of format "abscd", with s acting as a seperator character. The first section and the separator, abs will be the first half of the string, whereas the second half will be cd
The length of a will be (string length / 4) - 1
The length of b will be (string length / 4)
The length of s will be 1
The length of c will be (string length / 4) + 1
The length of d will be (string length / 4) - 1
This may be really confusing, so let me show you
with some examples
("a" + "bb" + "s" + "ccc" + "d").length //8
1 2 1 3 1
|-------4--------| |----4-----| <--- (4 is half of 8)
("rosen" + "crantz" + "&" + "guilden" + "stern").length //24
5 6 1 7 5
("foo" + "barr" + "?" + "barry" + "foo").length
3 4 1 5 3
Finally:
You then shuffle the parts around, outputting adscb
ex. "rosencrantz&guildenstern" --> "rosenstern&guildencrantz"
"foobarr?barryfoo" --> "foofoo?barrybarr"
Rulez:
Standard Loopholes are prohibited- Acceptable answers: a function which takes input through one input string and returns one output string
- If the input string doesn't match the requirements provided above,
your code MUST error out(doesn't matter what kind ofExceptionorError) - This is
code-golf, so the shortest(valid)answer (in each language)
wins!
Bonus points for a one-liner :-) (Not really tho, just cool points)

@JonathanFrech I think the challenge of input validation is an interesting problem, as it can be handled a variety of ways from array traversal, to branching logic, to RegEx testing, so optimization of these can add a extra challenge ¯_(ツ)_/¯ I'll try that for another code golf challenge though :-)

Perl 6, 78 bytes
*.comb[0..*/4-2,3* */4+1..*,*/2-1/(*>7)..3* */4,*/4-1/(*%%4)..*/2-2].flat.join
Try it online!
Anonymous code block that takes a string and returns the modified string if valid, else returns a division by zero error. I know I can modify an array directly, so I could swap the two sections of the string, but I can't quite figure it out.

Returns an empty string if the input string length is not divisible by 4. Also assumes adscb order, as implied by the examples.
