I happen to have four SCSI units to be wired up
they need to be hosted inside a metal tower
two of these units are 68p/f, while the other two are 50p/m
the SCSI topology doesn't allow branches and T-something
along the chain ... therefore I am in a trouble
buy? what? from who? to do what? and can I buy one-shot?
hey oh? keep calm, don't drink too much coffee 
Daisy chain?
yes
so, the new topology should look this way
external | internal
host_cable ---- HD68/female ---+
bracket
+----68p/female-----+1
|
2+-- 68p/female unit1
|
3+-- 68p/female unit2
|
+----68p/female-----+4
bracket
term ---- HD68/female --+
external | internal
host_cable ---- HD68/female ---+
bracket
+----68p/female-----+1
|
2+-- adapter(68p/male,50p/female) --- 50p/male unit1
|
3+-- adapter(68p/male,50p/female) --- 50p/male unit2
|
+----68p/female-----+4
bracket
term ---- HD68/female --+
internal cable:
68p/male ---- 68p/male ---- 68p/male ---- 68p/male
(1) (2) (3) (4)

HD68/female --- bracket --- 68p/female

do you know a shop, or a company, which realizes a customized SCSI cable ?
SCSI lvd/8 bit on channel1, and lvd/16bit on channel2

I did in 1998. SCSI is a bit out of the mainstream these days. There is a place near me called "Apache Reclamation" that has stuff like that. Call or email, cause they (obviously) don't keep their inventory up to date.
the golden age is gone, till Ultra-320 it's been a good double decade
with Ultra-640/Fast-320) it doubles the interface speed yet again,
up to 640 Mbyte/sec, even if manufacturers have skipped
and .... are developing for Serial Attached SCSI instead
today we still have SCSI, we have SAS
