Ok! A coworker helped me noodle this through; turns out the input required for dialog is rather odd...

Code:
#! /bin/bash
#usage: Dynamic_Menu.bash /home/user/target_directory
declare -a array

i=1 #Index counter for adding to array
j=1 #Option menu value generator

while read line
do		
#Dynamic dialogs require an array that has a staggered structure
#array[1]=1
#array[2]=First_Menu_Option
#array[3]=2
#array[4]=Second_Menu_Option

	array[ $i ]=$j
	(( j++ ))
	array[ ($i + 1) ]=$line
        (( i=($i+2) ))
	
done < <(find $1 -type f) #consume file path provided as argument

##uncomment for debug
#printf '%s\n' "${array[@]}"
#read -rsp "Press any key to continue..." -n1 key

#Build the menu with dynamic content
TERMINAL=$(tty) #Gather current terminal session for appropriate redirection
HEIGHT=20
WIDTH=76
CHOICE_HEIGHT=16
BACKTITLE="Back_Title"
TITLE="Dynamic Dialog"
MENU="Choose a file:"

CHOICE=$(dialog --clear \
                --backtitle "$BACKTITLE" \
                --title "$TITLE" \
                --menu "$MENU" \
                $HEIGHT $WIDTH $CHOICE_HEIGHT \
                "${array[@]}" \
                2>&1 >$TERMINAL)

I haven't fully debugged this yet, but from a directory with less than 10 files it's working!

tk_chooseDirectory(n)					       Tk Built-In Commands					     tk_chooseDirectory(n)

__________________________________________________________________________________________________________________________________________________

NAME

       tk_chooseDirectory - pops up a dialog box for the user to select a directory.

SYNOPSIS

       tk_chooseDirectory ?option value ...?
_________________________________________________________________

DESCRIPTION

       The  procedure tk_chooseDirectory pops up a dialog box for the user to select a directory. The following option-value pairs are possible as
       command line arguments:

       -initialdir dirname
	      Specifies that the directories in directory should be displayed when the dialog pops up. If this parameter is  not  specified,  then
	      the  directories	in  the current working directory are displayed. If the parameter specifies a relative path, the return value will
	      convert the relative path to an absolute path.

       -mustexist boolean
	      Specifies whether the user may specify non-existent directories.	If this parameter is true, then the user may only select  directo-
	      ries that already exist.	The default value is false.

       -parent window
	      Makes window the logical parent of the dialog. The dialog is displayed on top of its parent window. On Mac OS X, this turns the file
	      dialog into a sheet attached to the parent window.

       -title titleString
	      Specifies a string to display as the title of the dialog box. If this option is not specified, then a default  title  will  be  dis-
	      played.

EXAMPLE

	      set dir [tk_chooseDirectory 
		      -initialdir ~ -title "Choose a directory"]
	      if {$dir eq ""} {
		 label .l -text "No directory selected"
	      } else {
		 label .l -text "Selected $dir"
	      }
