Doesn't really help.
Eg.

--------------------8<--------------------
TLIST = "/tmp/dir with space/one" "/tmp/another spacey thing/two"

tlist=
.for t in ${TLIST}
tlist+= ${t:tW:S, ,?,g:S,",,g}
# the above :tW causes the value to be treated as one-word
.endfor

all:
	@echo TLIST='${TLIST}'
	@echo tlist='${tlist}'
--------------------8<--------------------
$ make
TLIST="/tmp/dir with space/one" "/tmp/another spacey thing/two"
tlist= /tmp/dir?with?space/one /tmp/another?spacey?thing/two
$

but when we try to use ${tlist} as targets:

--------------------8<--------------------
TLIST = "/tmp/dir with space/one" "/tmp/another spacey thing/two"

tlist=
.for t in ${TLIST}
tlist+= ${t:tW:S, ,?,g:S,",,g}
.endfor

all: ${tlist}
	@echo TLIST='${TLIST}'
	@echo tlist='${tlist}'

${tlist}: .PHONY
	@echo "making: '$@'"
--------------------8<--------------------
$ make
TLIST="/tmp/dir with space/one" "/tmp/another spacey thing/two"
tlist= /tmp/dir?with?space/one /tmp/another?spacey?thing/two
$

note we don't get 'making...'
If we replace ? with . it works but that isn't very useful:

all: ${tlist:S,?,.,g}
        @echo TLIST='${TLIST}'
        @echo tlist='${tlist}'

${tlist:S,?,.,g}: .PHONY
        @echo "making: '$@'"

$ make
making: '/tmp/dir.with.space/one'
making: '/tmp/another.spacey.thing/two'
TLIST="/tmp/dir with space/one" "/tmp/another spacey thing/two"
tlist= /tmp/dir?with?space/one /tmp/another?spacey?thing/two
$
