I propose:

for a portal you need to:

• kill a chicken or snow golem
• in an area
• with all (most? many? of) the features of spookytime available in the overworld in the area
• with the lights out
• with a tiny pumpkin
• When the chicken dies there's a "Squash!" sound effect
• A witched pumpkin is placed where the chicken died
• and the surroundings fade to the spooky dimension
• if there aren't enough spooky things in the area, the chicken dies with a "Sqawk!" or something instead

intercepted progress: what if nether portals bring you to the spook the first time you go in one :)

me likey
and randomly afterwards
bonus points if you dont put it in the mod description

Require it to be night time and a witch within a certain distance to open an altar. The altar requires jack o lanterns, a few lanterns, a few bits of water (these will be witched) and pumpkin in the center. Some block from the nether as a sort of base.

After the altar is built drop the anvil onto the pumpkin in the center and the gate opening sequence will begin.

Of course the sequence has to involve some amount of lightning.

Nah mate make the altars naturally generated structures in the overworld :P

But you have to activate them

Implemented and working

This seems a bit convoluted

How about dying to a witch after being tricked instead of treated does the following:

• puts a witched pumpkin where you died
• sends you to the spooky dimension, optionally leaving your items behind

That's heavily chance-based, which I don't like the idea of.

Or you could build a ring of Jack-o-Lanterns and drop something in the center to create a spooky portal

Some requirements for the mechanic?

before we get into specifics
it seems my ideas were off course

• possible nether gate
• easy to get to the Spook after going there once
• preferably spooky?
• sure to work
  • not finnicky
    • not requiring a large structure
    • not chance based
  • repeatable

1. gated behind the nether (as in, you need to get something from the nether to be able to get into the spooklands)
2. not too convoluted, we don't want it to have too complex of a set up
3. avoid being chance-based

however, we can make it based on something like phases of the moon or something you'd have to wait for provided that there be a non-time gated way to travel there after doing the initial travel

falling into lava in the nether while wearing a pumpkin from a height that would otherwise kill you?

You can only activate the portal at night during a full moon maybe, but afterwards it's always available.

eating magma cream while trick or treating?

During a Full Moon, drop a piece of sugar, a blaze rod, and some more items on a Lit Jack-O-Lantern. The Jack-O-Lantern will be converted into some kind of portal pumpkin which, while stood on, will transport you to the dimension.
