Is there a way of having a 64bit assembly written function imported(using extern/endextern) in a normal 32bit blitz app and then used to create a thread from that function?

No.
you can try using BlitzmaxNG which is a port of Blitzmax that can compile 64bit executables.

Tried this:

"main.bmx"

Import "a.s"

Extern 
	Function f()="f"
EndExtern

"a.s"

format ms coff 

section "code" code

Public f as "_f"
f: 

	ret

Output:

NG uses the gcc compiler toolset so you need to write assembler to the appropriate syntax. Googling for the same version of gcc that NG is compiling with, ie 'gcc version as manual', would be best.

Test.bmx

Strict

Import "test.s"

Extern"c"
	Function func()
EndExtern

Print func()

test.s


.globl func

func:
	mov $20,%rax
	ret

you can also change the syntax with the appropriate compiler switches..

.intel_syntax noprefix
.globl func

func:
	mov rax,30
	ret
