Thanks for you response MichaelH.

Below is the solution I have been working on this afternoon. Thought I would post incase it is of any use to anyone in future. It’s a page template which provides a starting point for building an alternative registation form. This will allow creation of a customised registration form without hacking at the core wordpress files. It is also unaffected by any plugins overiding the default registration page (i.e. Register Plus or Pie Register).

I would welcome any feedback as to how this might be improved.

<?php
/*
Template Name: ALTERNATIVE USER REG
*/
	// FUNCTION TO PREVENT DATABASE ATTACK - BEGIN
		function check_input($value){

			// Stripslashes
			if (get_magic_quotes_gpc()){
				$value = stripslashes($value);
			}

			// Quote if not a number
			if (!is_numeric($value)){
				$value = mysql_real_escape_string($value);
			}
			return $value;
		}
	// FUNCTION TO PREVENT DATABASE ATTACK - END

	// CHECK TO SEE IF FORM HAS BEEN SUBMITTED
	if($_POST['SubmitCheck']==1){

		// CHECK TO ENSURE THAT USERNAME & PASSWORD FIELDS HAVE BEEN FILLED IN
		if((trim($_POST['UserName'])=="") || (trim($_POST['Email'])=="")){
			echo "Please enter a valid Username/Password";
		}
		else{

			//GET VALUES SUBMITTED VIA FORM
			$user_name = check_input($_POST['UserName']);
			$user_email = check_input($_POST['Email']);

			// GET REQUIRED WORDPRESS LIBRARIES
			require_once(ABSPATH . WPINC . '/registration.php');
			require_once(ABSPATH . WPINC . '/pluggable.php');

			// CHECK WHETHER USERNAME EXISTS
			if(username_exists($user_name)){
				echo "This username already exists. Please enter another.";
			}
			else{

				// CHECK WHETHER EMAIL ALREADY EXISTS
				if(email_exists($user_email)){
					echo "This email already exists. Please enter another.";
				}
				else{

					// GENERATE A RANDOM PASSWORD
					$random_password = wp_generate_password( 12, false );				

					//CREATE THE WORDPRESS USER
					$user_id = wp_create_user( $user_name, $random_password, $user_email );				

					// SEND USER AND DATABASE ADMIN THE NOTIFICATION EMAIL
					wp_new_user_notification( $user_id, $plaintext_pass );

					// THANK YOU MESSAGE
					echo "Thank you for registering. Please check your email.";			

				}
			}
		}
	}
	else{

		// IF THE FORM HASN'T BEEN SUBMITTED, OUTPUT THE REGISTRATION FORM

		echo	'<form name="input" action="'.get_permalink().'" method="post">';

		echo		'<p>Username:<br /><input type="text" name="UserName" /></p>';
		echo		'<p>Email:<br /><input type="text" name="Email" /></p>';
		echo		'<input type="hidden" name="SubmitCheck" value="1" />';
		echo		'<p><input type="submit" value="Submit" /></p>';

		echo	'</form>';
